Joint RASS - MixSS Webinar on January 11: Mixture Assessment Factors – Motivations, Derivations and Uses
Hosted by: SOT Risk Assessment Specialty Section and Mixtures Specialty Section

Mixture assessment factors have been proposed as a regulatory instrument for dealing with combined exposures to multiple chemicals. Their use is motivated by the realization that risks from combined exposures may arise even when each component in the mixture complies with its regulatory exposure limits. Since assessment factors in common use for the setting of single chemical exposure limits cannot accommodate mixture risks, an additional factor, the mixture assessment factor, is suggested to mitigate mixture risks.
This presentation will give a brief historical introduction to the genesis of the idea of a mixture assessment factor. Case studies from human toxicology and ecotoxicology will be used to illustrate the need for a mixture assessment factor. Various approaches for quantitative derivations of such factors will be presented and discussed. Finally, a summary of the policy context for implementing mixture assessment factors in the European Union will be given.
